[mythtv-users] Re: 1000th picture quality question

[Mark L. Cukier]

The fact that DVD looks perfect SHOULD tell us that it's a problem with 
our capture or decoding, rather than with our Video Driver, right? (I 
haven't compiled MythDVD yet, but I'm going to do so tonight and let you 
know...)

I set my bitrate to the maximum, and all I saw chage was the fact that 
the recording would get INCREDIBLY choppy!!! My PVR-350 seemed incapable 
of recording at 16Mbps... did you guys observe this as well?
